Embodiment Construction

[0024] A metal film reflector includes a glass substrate 1. On the composite surface of the glass substrate 1, six film layers are sequentially and adjacently composited from inside to outside. The first film layer is the innermost layer. SiO 2 Layer 21, the second layer is Al 2 O 3 Layer 22, the third layer is Ag layer 23, and the fourth layer is Al 2 O 3 Layer 24, the fifth layer is SiO 2 Layer 25, the outermost layer is TiO 2 Layer 26.

[0025] The first film layer SiO 2 Layer 21, the silicon dioxide layer, as a base film, has a higher transmittance and a lower refractive index, SiO 2 The thickness of the layer 21 is 5-15 nm. nm is nanometer, 1m=10 9 nm.

[0026] Al of the second film layer 2 O 3 The layer 22, the aluminum oxide layer, serves as a transition layer that increases the adhesion of the Ag layer. Al 2 O 3 The thickness of the layer is 10-20 nm.

[0027] The Ag layer 23 of the third film layer, that is, the metallic silver layer, serves as the main reflection layer, s...

Abstract

The invention discloses a metallic film reflector which comprises a glass substrate, wherein a compounded surface of the glass substrate is sequentially and adjacently compounded with six film layers from the inside to the outside. The metallic film reflector is characterized in that the first film layer is a SiO2 layer as the innermost layer; the second layer is an Al2O3 layer; the third layer is an Ag layer; the fourth layer is an Al2O3 layer; the fifth layer is a SiO2 layer; the outermost layer is a TiO2 layer. The invention aims at overcoming the defects in the prior art, provides the metallic film reflector with the advantages of high transmittance, high reflectivity, low refractive index as well as good mechanical properties and strong adhesive force of film layers and also provides a manufacturing method for the metallic film reflector.

Description

【Technical Field】 [0001] The invention relates to a reflecting mirror, more specifically a metal film reflecting mirror. The invention also relates to a manufacturing method of the metal film reflector. 【Background technique】 [0002] Mirrors are commonly used industrial products in daily life and modern architecture. The use of mirrors brings a lot of convenience to production and life. The existing reflector has low reflectivity and unsatisfactory imaging effect. [Content of the invention] [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a metal film reflector with high transmittance, high reflectivity, low refractive index, good mechanical properties, and strong adhesion. The invention also provides a manufacturing method of the metal film reflector. [0004] The present invention is realized through the following technical solutions: [0005] A metal film reflector, comprising a glass substrate 1. On the composite surf...
